Insulation

Michael a C. Wilmington, DE

I need to insulate over the garage to keep the heat down during the summer. It's about 600 square feet. I don't know if the soffit vents were prepped to prevent blockage by blown-in insulation, so we could go with bats/rolled if need be. I think 4-6" would be enough.
